All KPMI Black Diamond Stainless Steel Valves are impregnated by a special German process to .002” deep with a .0002” surface build-up to improve wear properties and reduce friction. This process provides resistance to corrosion and wear that is superior to that developed by hard chromium and electrolysis nickel plating. These valves are light and the profiles provide excellent flow characteristics.
